can anyone help me in designing a bandpass filter for 2GHz to 6GHz using microstripline
i would mainly like to know how the lumped elements are converted to striplines.
thanks in advance
The main idea is that a lambda quarter transmission line would act like a LC resonator.
There are plenty of topologies to implement a bandpass filter, like:
End-Coupled Half-Wavelength Resonator Filters
Parallel-Coupled Half-Wavelength Resonator Filters
Hairpin-Line Bandpass Filters
Interdigital Bandpass Filters
Combline Filters
Pseudocombline Filters
Stub Bandpass Filters
Maybe for your application I may recomend a levy uwb filter. There is some introduction at my bachelor degree thesis (point 2.2.2) :
